Not a game but you can play around with different configurations.Switching between configurations can create some interesting patterns.Especially the 'labyrinth' was new to me, 'copy world' looks cool if you start with few cells.

This is strange, I just checked it with -Xmx40m and it works fine.It should work with the default 64m, after loading the game, 22.2m are used.Maybe more RAM is temporarily needed, but it should really work with 64m. And the applet had the 64m in your case (I log it)

Did you disallow applets to grab more RAM (than 64m) with applet tags by hand or is that a standard feature of Opera?
